We experienced similar peer to peer OM table issues and finally figured out that it was associated with trying to change a peer to peer sink connection from one variable to another in the same session. Seemed to be if the source block was deleted in CP1 before removing the sink connection to the deleted block in CP2 and then going to the sink block in Cp2 and changing the bad connection to a valid connection. This could cause the OM table to shift references. The sink block connection looked ok but was pointed to the wrong source variable in the OM table. Very insideous. Once the OM table was hosed the only way we found to fix it was a sink CP reboot. Our work around was: Always remove the sink connection 1st Then checkpoint sink CP Remove the old source block from the source CP Checkpoint the source CP Add the new sink connection Checkpoint the sink CP Tom Sent from my Verizon Wireless BlackBerry -----Original Message----- From: Michael Kessler <mkessler@xxxxxxxxxxxxx> Sender: foxboro-bounce@xxxxxxxxxxxxx Date: Mon, 27 Aug 2012 12:46:10 To: foxboro<foxboro@xxxxxxxxxxxxx> Reply-To: foxboro@xxxxxxxxxxxxx Subject: [foxboro] Peer to Peer connection good but not updating I have some peer to peer connections between calcA blocks in ZCP's that are not updating. (XXX.BO01 > YYY.BI01) I've deleted/undeleted the blocks, with no success. Deleting the source block does not turn the sink point Cyan which should normally be the case. I am able to see the status of the source using omget. I suspect corrupt OM lists. Will a re-boot clear these up or is a CP initialize/loadall required? Anyone experienced this type of problem? mk _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
